    • A flux cored, gas shielded arc welding electrode for depositing a weld metal with low diffusible hydrogen and having tensile strength greater than 90 Kpsi and a yield strength greater than 80 Kpsi. The electrode includes a nickel free steel sheath with a carbon content of less than 0.05% of the sheath and a core in the range of 13-17% of the electrode wherein the core includes primary alloy particles of iron, manganese, magnesium and nickel with a minor amount of secondary alloy particles of a silicon alloy and a boron alloy in a rutile based slag system. The nickel has a controlled amount in the general range of 1.0-2.0% by weight of the electrode and the rutile is 40-60% by weight of the core.
    • 一种用于沉积具有低扩散氢的焊接金属并具有大于90Kpsi的拉伸强度和屈服强度大于80Kpsi的药芯焊接气体保护电弧焊接电极。 该电极包括碳含量小于护套的0.05%的无镍钢护套和在电极的13-17%范围内的芯,其中芯包括铁,锰,镁和镍的初级合金颗粒, 在金红石型炉渣系统中少量的硅合金和硼合金的二次合金颗粒。 镍的电导率为1.0〜2.0重量%,金红石为核心重量的40〜60重量%。
